Question

Compller A Compler B Execution Ti Execution Time No. Instructions meNo. Instructions b. 1.9 s 1.60E+09 1.30E+09 2.1 s 1.71 [5] <1.4> For the same program, two different compilers are used. The table above shows the execution time of the two different compiled programs. Find the average CPI for each program given that the processor has a clock cycle time of 1 ns. 1.7.2 [5] <1.4> Assume the compiled programs run on two different processors If the execution times on the two pro cessors are the same, how much faster is the clock of the processor running compiler A's code versus the clock of the processor running compiler B's code? 1.7.3 [5] <1.4> A new compiler is developed that uses only 350 million instruc- tions and has an average CPI of 1.7. What is the speedup of using this new compiler versus using Compiler A or B on the original processor of 1.7.1?
